Neptune is the brightest object in these images spanning two weeks. The planet moves from the upper right toward the lower left against the background stars. See the bright grouping of stars in the middle left of the first image. Notice how Neptune passes right by this grouping on the night of September 3 and is well left of the grouping by September 10. If you look closely you can see Neptune's largest moon Triton making the journey along with the planet.  Its orbit about the planet is clearly visible. Click on each image above for a close up of the moon and planet.
